the fact that it only works after warming up makes me suspect capacitors on psu, motherboard, or video card.

He doesn't have a display problem. Even if the gpu was fragged, his pc would start just fine. However, unless the psu is replaced, it's only a matter of time before he sees smoke coming out...

not really. acer uses delta PSUS in their stuff.

i used to drive an athlon 3500+, a 4650 all with a psu rated for just 200W.
delta electronics is pretty good. but i am not sure what they are using now.

hey, BIG boi, is the whole config stock? because OEMs will lock the bios to prevent upgrading.

Nabarun · Aug 25, 2013

Well, if it's not the psu, then it probably IS the motherboard. We"ll just have to wait and see, until he tries a different psu.

BigBoi · Aug 26, 2013

hi guys!
thanks for all of your time!

i bought a new psu (corsair) and motherboard (gigabyte) yesterday, and immediately installed everything, sorry i didnt even think about trying to plug the PSU first, as i want to resolve it ASAP lol :laugh:

everything was installed yesterday, and immediately worked, but the true test was this morning when i fired it up, and it came on immediately! :toast:

i have one itsy bit of an issue, though,:
im pretty sure i correctly installed the speaker that came with my chassis, but it doesnt give me a beep sound on post/boot...

again thank you guys! cheers!

PS
in a few months ill be assembling a new rig to replace this old system (but im still keeping it).
and hope to have the same help if not more from you guys in picking parts...
:rockout:

Either the speaker is NG or you have the wires on the wrong pins. Double check your manual.

Nabarun · Aug 26, 2013

Glad your problem's gone, but would be nicer to have known the exact cause of it. Anyway, congrats on your *new* stuff

yeah, i know. and i'm sorry.

...BUT!!!!

i tried my old PSU first on my friend's computer last weekend just for us to find out,
and it's working fine.
also tried my mobo, and does the same thing. so there we have it, the motherboard gve up on me..

brandonwh64 · Sep 11, 2013

My psu at work is doing the same thing. It started on my AMD combo I had and continued with the X58 I have now. If I power the machine all the way down and turn off the PSU power or unplug it then it will almost refuse to turn on with the power button. I have to turn it on and off a couple of times from the PSU to get it to power the motherboard on but since I run this machine as a cruncher (24/7 100% load) its fine with me but if I have to take it apart for repairs or upgrades its a pain to get started again.

See, you wouldn't have to buy the psu if you had tried those ...

nah, i was going tto either way.
the old one was old and it wont reach my 24 pin and 8 pin slots.
old case was top mounted so there you go

No kidding :laugh:

Hi all,

Just to let know that I'm in exact same situation as BigBoi was: 4,5 year old Acer Aspire m5711 and the same simptoms apply (vacuum loud fan and computer doesn't startup). The problem is that it only happens sometimes but in my case the power button always lights up.
I'm willing to do some experiments.

try to change the motherboard first.

I was hoping for a cost-free experiment.... I'm not paying for a new expensive motherboard without being sure that solves my problem.

You can send the board back within 30 days for a full refund if it doesn't work.

the only way to do that i think is to find a friend or someone you know that has a G41 or something motherboard, or other parts that is compatible with what you have.
the reason that i bought new parts for my pc is because i use it everyday and i dont have an extra computer (besides the fact that i love it so much :oops:

) and i was pretty sure it was the motherboard.

if you want, try to change the thermal paste on your CPU. maybe that's the issue

itsakjt · Jan 18, 2014

The first thing you should do is take out the CMOS battery, short the terminals and then attempt to start the system. The next step is to remove all the RAMs and start the system without any RAM installed. You should get a series of beeps(continuous for Award Phoenix BIOS and 3 beeps for AMI BIOS) from the motherboard speaker/speaker via header. If you don't get such beeps, it is definitely the board, CPU or PSU. All the best.

nmrm · Jul 11, 2014

I replaced the motherboard with a clone a few months ago but it didn't fix. It was not from the motherboard as I saw the symptons again although now it's better, maybe because of the hot weather :confused:

I notice that unplugging some usb/eth cables on the back of the motherboard helped the computer to successfully boot.
Any expertise advice? Thx

The psu is at fault

You need to run some testing on memory, psu, etc.
Swap parts or try yours in another system...

Not to be mean; however, you need to start your own thread as it can cause confusion in the thread.
